Great summary!
Yes, many people do not know that there are two types of colour models and that we construct black and white by addition and subtraction.
I was painting quite a lot, so I am quite used to mixing pigments, but it must be a completely different issue to mix lights. Once I saw a theatre performance where the light technician wasn't on top, all of the actors on stage looked like zombies... though it was a classic Shakespeare play and they probably intended to create sunny daylight... it was quite funny...
Resteemed your post, it is a good addition to my series! :-)
